OM3023 10/00 Operation - Section 3 Operating Instructions Page 3-17 When moving the range selector lever from "N" to "R", or from "D" to 5, the Release Button on the end of the handle (operator side) must be pressed before the selector lever can be moved. "R" - REVERSE position - Bring truck to a complete stop before shifting from DRIVE to REVERSE or vice-versa. The Reverse Warning Horn is activated when REVERSE position is selected. "N" - NEUTRAL position - is used when starting the engine, during loading operations and parking the truck with engine running. The truck cannot be started unless the range selector is in the "N" - NEUTRAL position.
"D" - DRIVE position - When starting from a stopped position, the transmis- sion will shift automatically to second gear. As the truck ground speed increases, the transmission will automatically upshift through each gear to seventh gear operation. As the truck ground speed slows down, the transmission will automatically downshift to the correct gear for grade/load/engine conditions. NOTE: The transmission will be locked into second gear if the body is not seated on the frame. Always lower the body when traveling. 5, 4, 3" positions - Road and load conditions sometimes make it desir- able to limit the automatic up-shifting to a lower range.
These positions provide more effective retard- ing on grades. When the range selector is placed in any one of these positions, the transmission will not shift above the highest gear range selected. It will also downshift to first range when required by grade/ load/engine conditions. When conditions permit, select position "D" for normal operation. FIGURE 3-2. CENTER CONSOLE 1.

NOTE: The transmission will be locked into first gear if the body is not seated on the frame. Always lower the body when traveling.
